(o .'1s9 7)1 v The" invention relates to locking and operating mechanism for sliding doors, preferably operable from a remote point or station and pri- V marily for controlling aplurality of doors of cells or compartments of penal and-other institutions; r

An object of the invention is to provide asliding door operatingand locking mechanism of I greater durability and tamper proof, within the region of thedoor and which safeguards against oversight or negligence on the part of an attendant againstany ineffective locking of the doors 'which might result through any'incom plete operation of the control mechanism. 1'5" Another object of'the invention is to provide a sliding door operating and locking mechanisni'for a pluralityof doors of a rowof cells or compartments, operable from a station pref-- erably at one end of the row for either selec- 2'0 tively "or simultaneously unlocking, opening, closing, and relockingany and all of the doors, and the doors au'tomatically locked at the ex tremes of door slide. v

Other features and advantages of the invention will be more fully set forth in the description of the accompanying drawings, in whichi Figure 1 is a frontelevation of 'a'pairof cell sliding doors, one-in'open position and the second-closed with the improved mechanism for sliding/the doors either selectively or simultaneously, and locking the same either open or closed by'an actuating and control mechanis located at one end of a row of cells. r

Figures 14 to 16 ,inclusive,"are views similarto Figure 13, illustrating various stepsin the operation of the door; 1

In jails,iprisons, or other likeinstitutions, the cells or compartments are usually placed in rows, each cell of the row openingto a common corridor-or passageway, with a sliding 'door as a closure for the opening. .The doors usuallyv are operated-from a remote point or station, generally at the end=of 'a'row, for opening. and closing, and-to lock-the doors either in'open, partially open, 'or closed positions; With the present invention, it is possible to operate any one IOfthB doors of a series individually and-at random, forthe series, several or all simultaneously andnin selective groups.

The operating and locking mechanism for each of'the doorsof a series is of duplicate construction and connected witha common" actuating bar or rod extending along the row of doors.

Referring to the drawings, 1 indicates a-door, its upper end having arr-angle plate hanger 2, fixed thereon, the hanger carrying a pair of rollers 33, rolling upon a track-4,-the'track constituting-an angle iron bar suitably fixed to the frame-workor-frontwall of the cell. The hanging fixtures for the door may be of any type of construction for afree sliding of the door and to secure it against vertical displacement. v The bottom of the door is held in alignment byasuitable channel guide 6 and the front edge of the door when the door is 'closed, engages into achannel of a jamb '7. The lamb is of hollow post construction to enclose -a=sliding lock bar 8, the iockbar' engaging withone or several lock lugs 9, extendingfrom' the forward edge of the door and engaged-through a lock slot 11 in the door jamb when the door is closed.-

As'shown in Figure 3 of'the drawings, the door at its lower edge has a lock lug'9 fixed thereto and extending horizontally therefrom adapting the same to enter a slot-1'1 inth'e door 'jamb, upon closing the door, and ,be engaged by the lock bar 8. The lock lug has its forward end upturned tooverlap the lock bar 8, the lock bar resting upon the lug, when the parts are locked and when the door'is opened the lock-barserves as a closure plate for the lock slot in the Jamb.

A bracket p1atel2 is rigidlyattached'to the door hanger'Z, approximately intermediate or the'door' guide rollers to which a door locking and coupling link 13 is pivoted, the link extending forwardly and its forward end provided with a laterally extended lug 14 in a lowermost position engaging or resting upon the horizontal slide bar 15 and in an alternate or upward position for sliding upon a stationary rail 16. The rail is of angle iron form fixed to the frame-work or front wall of the cell, and the slide or coupling operating bar is mounted upon the vertical limb of the angle iron rail by means of studs 1'7, each engaged through an elongated slot 18 in the slide bar to allow the bar to be reciprocated. The slide bar 15 is provided with a cam tooth 19 projecting from the upper edge of the bar for engaging the laterally extending lug of the coupling link to swing the link upwardly, elevating the lug to a plane with the slide rail, unlatching the door and allowing the door to be slid for opening.

In the elevated position of the latch and coupling link 13, the laterally extended lug 14 is in a position for coupling to a shifter bar 20 parallel with the slide bar 15 as a medium ifor sliding the door and common to all of the doors of a series or row.

The shifter bar 20 is slidably mounted on the cell front and for each door of the series is provided with a pair of oppositely disposed latch lugs or pawls 21-21, pivotally mounted on the shifter bar, with the forward ends of the pawls spaced apart to engage the laterally extended lug 14 of the latch and coupling link 13 therebetween when the link has been elevated to bring its lug at a plane of the'guide-way. The latch pawls 21-21, each is provided with a laterally extending lug 22 overlapping the upper edge of the shifter bar forming a stop for limiting the downward swing of the pawl. The forward end of the latch pawl is provided with a cam edge23 for automatically lifting the pawl when engaging with the coupling link, and allowing the link to be engaged between the pawls.

A tripper dog 24 is pivotally mounted on the cell front, having an arm at the lower side of the pivot, adapted to rest upon the track or rail 4 and in the path of a roller 25 mounted upon the door hanger for actuating the dog in the opening and closing travel of the door. The do'gis provided with an upwardly" extending arm 26 with its upper free end having a laterally extending lug 27 projecting within a notch '28 in the upper edge of'the slide bar 15. A lug 29 extends upwardly from the slide bar 15 at the forward end of the notch and therewith provides a shoulder against which the laterally extending lug of the dog engages to connect with the slide bar for shifting or sliding the slide bar forwardly with each actuation of the dog, bringing the slide bar to a neutral position, and advancing the tooth a suitable distance from the end of the slide-way or rail 16 to allow the link 13 to drop off of the end of the slideway or rail when the door'has reached either open or closed positions, thereby locking the door in either extreme or travel.

To' positively lockthe'link in its downward position below the plane of the guide-rail in either extreme, opener closed position of the door, the slide bar 15; for locking the link against upward movement when the door isclosed, is provided with a laterally extending lug 3!) at an elevation to be brought in registry over a laterally extended lug 31 on the link '13 when the slide bar 15 is brought to an extreme forward position; When the door is at its extreme open position, the link is locked down by a latch lug 32 on the rear 3 end of the slide'bar 15 which hooks over the lateral lug of the link 13, securing the same against vertical lift.

When the door is closed, as shown for the second door in Figure 1, the slide bar 15 for that door, is in an extreme forward position, the link 13 resting on the top edge of the slide bar and adjacent the forward edge of the rail 16 thereby locking the door against opening. The link 13 is locked against vertical lift by the registration of the lugs 30-31, respectively on the slide bar and link. Upon shifting the slide bar to the right, lug 30 of the slide bar will be advanced, clearing the lug 31, leaving the link 13 free to be raised by the cam tooth 19, the cam tooth elevating the link to anelevation with the rail 16 and engaging the laterally extended lug 14 on the link between the coupling pawls 2l-21 of the actuating or shifting bar 20 connecting the link with the bar 20 and moving therewith upon reciprocating the bar for sliding the door.

As the door is opened by the shifter bar 20, the roller 25 on the hanger bracket, will engage the lever 24, shifting the slide bar 1-5 to a neutral position to the left, bringing the tooth 19 at the opposite end of the slide bar 15 inward of the end of the rail 16 so that the link can drop off of the right end of the rail upon the slide bar, engaged and locked down by the hook 32 at the extreme right end of the slide bar. The link 13, as it drops off of the end of the rail 16, is releasedv or retreats from its engagement between the pawls of the shifter bar, so as to again'require the slide bar 13 to be shifted to the right to elevate the link before the link can be recoupled to the shifter bar for a door closing operation. 7

The door, at its upper forwardend, is provided with a rigid lift wedge 33 for engaging with a roller 34 journalled and extending fromthe vertical lock bolt or bar 8 within .the jamb, to raise the lock bolt until thebottom latch lug 9 clears the lower end of the lock bolt and as the door continues to close, the roller 34, enters a notch in the lift wedge, allowing the lock bar to descend to its door locking position, bringing the lower end of the bolt in engagement with the lock lug 9.

The lock bolt or bar 8 is also raised by the slide bar 13 through a roller 35, journalled on said bar, engaging with a camlug 36, extending laterally from the upper end of the lock bolt 8. It is necessary to initially release the lock bolt 8 by the slide 12. bar 13 before the door can be released from'the lock bolt in its engagement with the latch bolt 9. The lock bolt is also adapted to be locked in its door locking position by a lug 37 extending laterally from the slide bar, engaging with the upper 130 end of the lock bolt 8, when the slide bar is in its extreme left position. This makes it impossible to raise the lock bolt 8 by any drift. inserted through the latch opening 11 beneath the lock bolt or by any other tampering method.

The shifter bar is reciprocated by a lever mechanism housed within a casing or cabinet at one end of a row of cells, the mechanism preferably comprising a vertically disposed lever 38 pivoted at its lower end to a bracket 39 fixed to the floor or bottom of the casing 40. The-upper end of the lever is pivotally connected to a link 41, the link in turn being pivotally connected with the forward end of the shifter bar 20. The lever 38 is actuated by a bell crank lever 42 of double construction to'straddle the lever 38; and the two sections, as a unit, are pivoted to a bracket 43 fixed to a vertical base wall of the casing 40. The short arms of the bell crank lever 42 are joined by a stud carrying the roller engaged through an elon- 150 gated slot 44 in the lever'38. The upper ends of the long arms of the bell crank lever are connected by a' handle' 45 projecting side-wise for ready grasp by the hands of the operator. The bracket 43 is arranged for vertical adjustment to change the "stroke of the lever, tocompens'ate forwe'ar, in the-lever and'parts attached-"thereto. With the bell 'cranklever 42 in this upward position as shown in Figure 1, the shifter barhasbeen moved to an extreme right or door opening position, and when in a position as shown in Figure 2;to a position fora complete closing of the door. 5 When the bell crank lever 42, in a position as shown in Figure 1, is swungdownwardly the lever 38 is pulled downwardly, causing the bar 20 to be moved forwardly to closethe doors. 'An operation-of the bell crank leverin areverse direction moves the shifter bar 20 in a direction for opening the doors. This lever mechanism provides'for a convenient and easy operation and without undue exertion on the part'of the operator to move'a large number of doors, the door in some instances being of considerable number, carrying. considerable weight, imposing a heavy load; F i The several extreme positions of -the bell crank lever renders the leverfm'echa'nis'm self-locking, making it impossible to shift the bar 20 from any point along'the 'row of cells for which the bar serves. "The slide bar 15 forindividuallycontrolling the operation of the several doors of the cells of a row or series is m'anually reciprocated' by a rod or shaft 46 extending longitudinally parallelwiththe shifterba'r 20 with'its forward end extending into the'casing 40, and coupled to the upper end' of a hand lever 47 mounted up'on'a bracket 48; fixed tothebase'wall of the casing, The" hand lever moveswithin astationary quad rant 49 rigidly fixed to the'base wall of the casing iflfandthe'wall is provided; with a plurality-bf notches onits undenside to receive a sprin pressed latch or detent 50, mounted -upon the hand-lever in its adjusted or set position, at either a neutral or a locking position. '-At the neutral position the hand leveris lockedby-a swinging hasp orfpawl51 to block or limit the movement'of the hand lever in one direction, preventing the hand lever frombeing' inadvertently pushed into its locking'position; The hasp or latch is manu-= allyrele'as'able' and must be held out while'the' hand lever is" shifted 't'o its locking-position.

To insure "that anoperatonwill'not failto posi tively lock the door, a spur 52 is rigidly attached to the "hand lever -''and extends at right angles therefrom and 'forwardlyto'enga'ge with the door of the casing or cabinet, and prevent the door from being closed while the hand lever is in an outward or neutral position. The spur is proportioned, requiring that the door of the casing can only be closed when the hand lever 47 is in I its positive locked position.

The upper end of the hand lever 4'7 terminates into a fork and engages with a collar 53, free upon the rod or shaft 46 and between a pair of collars 54-54, fixed to the shaft, which enables the shaft to be revolved. The shaft is revolved vertically disposed rack bar 59, slidably supported upon the rear wall of the casing with the upper endjof 'the'rackbar' in meshwith a pinion 60, splined-upon the shaft' ifiz' 'Thesh'aftefi is'pro vided with a key 61, one foreach door of the series and located on the shaft to-lie between apair of spaced lugs" 62- 62, projecting fromthe ,lide'bar 15. 5 v

form, of 1 door control mechanism is disclosed This-form permits a door tobecut out ordisengaged from theshifting bar 20,:while the door is inztransit or in intermediate positions, as. in the event movement of thedoor is' obstructed by a prisoner, the movement to theunobstructed doors may continue.

The slide bar for actuating the link 13 is of sectional construction, constituting a section 15a longitudinally slidable and corresponding to the forward end of the slide bar 15 previously described. The bar section 15a is coupled to a second section 15b slidable both longitudinally and vertically. Section 15b is supported by a pair of studs 65 respectively engaged through diagonal slots in the bar for raising or lowering the bar to bring the link 13 supported thereon, either into I or out of coupling connection with the shifter bar 20. The bar can be dropped at any point in the door transit, individually disconnecting it from the shifter bar 20, so as not to interfere with the continued movement of the shifter bar. The bar section 15b in its elevated position serves as a guide or slide-way for the link 13, substituting for the stationary slide-way of the construction heretofore described.

The stationary slide-way may be utilized for locking the door at any intermediate position, by providing it with one or a series of notches into which the link 13 engages when the bar section is set in its lowermost position or elevation.
